How many reactants are there?
DONE
Answers
Answer:
1
Explanation:
By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.
What is reactant?A reactant is a substance or can say a chemical compound that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products.
For example we take a reaction-
O₂(g) + H₂(g) → H₂O(g)
Here, O₂ and H₂ are the reactants and H₂O is the product.
A reactant is present 100% initially and after sometimes it reduces gradually to form product according to chemical kinetics.
Given, the picture shown and the colour and texture of the reactant is shown.
Therefore, By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.

Convection currents in Earth's mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle.
Answers
Answer:
True or False
Answer - True
Explanation:
The mantle convection clearly describes how the mantle moves, transferring heat from the white-hot core to the lithosphere. The mantle is usually being heated below and the cooling happens above and the general temperature of the area gets dropped over a long period of time.
Hot buoyant Magma is being transferred through convection currents, to the lithosphere at the plate boundaries and hot spots. Also, convection current moves cooler materials from the crust to the interior of the earth through a process that is widely known as subduction.
If you start with 3 moles of sodium and 3 moles of chlorine to produce sodium chloride, what is the limiting reagent?(You will need to balance
the equation first.)
Na + Cl2 -> NaCl A. They are equal B. Na C. Cl2 D. NaCl
Answers
Answer:
B. Na
Explanation:
Once balanced you get 2Na + Cl₂ ⇒ 2NaCl. Sodium is the limiting reagent because it would produce the smallest amount of the product (NaCl)–while chlorine is the excess reagent. Based off of the Na in the balanced equation, it would produce 3 moles of NaCl, and for Cl₂ it would produce an excess of 6 moles of NaCl. [It'd be wise to utilize stoichiometric factors to get a good grasp of this]

The non-metals are boron and carbon. The metal is aluminum and the metalloid is silicon.
Explanation:
non-metal = boron, carbon
metal = aluminum
metalloid = silicon
Non-metal = boron, carbon
Metal = aluminum
Metalloid = silicon
What is metal?A solid material which is lustrous, hard, shiny, malleable, and sonorous with good electrical and thermal conductivity.
Metal is an element which is typically hard, shiny, fusible, malleable, and ductile, with good electrical and thermal conductivity.
A nonmetal is an element that does not have the properties of a metal.
A metalloid is an element having intermediate properties of both metals and nonmetals.
Hence,
Non-metal = boron, carbon
Metal = aluminum

A student calculates the density of an unknown solid. The mass is 10.04 grams, and the volume is 8.21 cubic centimeters. How many significant figures should appear in the final answer
Answers
Answer:
1.22 g/cm³
Explanation:
Density = mass ÷ volume
Mass = 10.04 grams
Volume = 8.21 cubic centimeters
Density = mass ÷ volume
= 10.04 ÷ 8.21
= 1.2228989037758 g/cm³
Approximately
1.22 g/cm³ to 2 significant figure.
The final answer should be approximated to 2 significant figure because the mass and volume of the objective given is in 2 significant figure

Which periodic table trend is represented by the blue arrows?
Answers
Answer:
Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.
